Yeah, it is called EBAY, or CRAIGSLIST

After you sell your goods there, you can take your US Dollars and buy as much BitCoin as you want.
Only a TOTAL FOOL , complete idiot, or moron would go to a very small market, where it takes longer to sell goods, sell good for less, just because you insist on direct payment in BitCoin.
i can't tell if you are just trolling or too naive.
buying bitcoin is harder than selling goods for bitcoin when you want to easily acquire bitcoin. it takes a lot of jumps through a lot of hoops before you can sign up on a risky exchange that can either scam you or close your account for whatever reason they want.
- then you have to pay a lot of fees to transfer your fiat to exchange bank account and risk your bank closing your account,
- then pay another fee to exchange that fiat to bitcoin
- then pay another fee to withdraw that bitcoin from your account to a wallet
in comparison all selling goods directly to bitcoin is super easy since it has no middle men, no additional fees and more importantly no risks of the middle man (aka banks and exchanges) scamming you.
You are a special kind of STUPID. You ignore the gorilla in the room, by trying to sell good in BitCoin you ELIMINATE 99.999 % of your potential customers. That means lower price and very long time to sell.
You are so emotionally attached to the idea of BitCoin, that you totally ignore reality and facts. A perfect example of a Cult Like " believer "....
